Application filed. August 15, 1918. Serial No. 249,965. I

To all whom it may concern:

Be it known that we, FnANors CHARLES SoUTHAnn and HENRY GEORGESOUTHARD,engineers, subjects of the King of Great Britain, residing at 15Bellevue Terrace, in the county borough of Southampton, Hants, England,have invented certain new and useful Improvements in Machines forRolling in the Base-Plates of High-Explosive Shells and Such like, ofwhich the following isa specification.

This invention relates to improved means and apparatus for fixing 1n thebase plates of high explosive shells by means of rolling,

for the shells, so thatthey are free to revolve on their axes under theaction of the'roller,

and that they may be easily inserted and extracted. The driving rollermay be either smooth or corrugatedto any suitable form for the purpose.

Other roller or rollers may be provided of suitable form and in suitablepositions to finish olf the rolling process and oppose the thrust of thedrivingroller. Means arealso provided whereby the roller or rollers canbe adjusted laterally across the base of the shell to bringthem in themost convenient position for working.

Having thus generally described the object and nature of the invention,we will now proceed to describe itwith reference to the accompanyingdrawings, which are marked with" letters and figures of referencecorresponding with those used in the following explanation. I, 1 1 a Inthe drawings Figure l is an endelevation, Fig. 2 a side elevation, Fig."3 a plan view, and Figs. 4c, 5 and Gdetails of the apparatus. Figs; 7and 8 are longitudinal sections'showing one of the forms of shell onwhich the apparatus is adapted to operate.

With reference to the drawings, A designates thebed'plate which issupported on the frame B, and C, C denote the shell holders which arepivotally fixed on the centers D, D. I The shell holders G, C areprovided 7 with roller bearings E, E, and with'thrus't bearings at'F, F.The shell'holders .C, C are H when it is desired to swing out the shellholders C, C. The holders C, C are preventthuscausing the shells L, L toapproach and press upon the roller M', L designates the base platesadapted to be rolled into the head pulled downward by means of a footpedal of the shell L. Motion is given to the levers K, K by the leversN, N and tension rods 0, O. The pressure applying'lever T is mounted onand turns, a shaft U journaled ina' suitablebracket 'U. The'l'ever N isecthus placing levers K under action of the weight P withthe resultthatthe head of the lever K is forced inward against the'shellholders. Bythis means a most even feeding centrically' mountedirel ative' to shaftU on of the Work to the tool isieifectedund'er ac tion of weighted rodQ. Y

The action of moving the fulcrum of the lever N nearer to-the lever Khas the effect of reacting on the weight and raising it' from its loweror restlng positlon so-that 1t exerts its pressure 'which is multipliedby the-system of levers and tension rods before mentioned;

Equal pressure upon the two shells 1s assured by the fulcrim v of thelever Q being when one side is'worn out it can be turned a 7 base plate;

over and the unused part brought into aetion) is mounted upon a shaft X,which is caused to revolve in a bearing Y by the'pul ley Z, and thethrust of the roller is taken by the bearing 2. The bearing Y is adjustable laterally by the hand wheel'3' and-the screw 4, and itstravel islimited by projec tion 5 of the bearing Y and screw adjusted limit stops5. Although specially designed for 18 Pdr hi h explosive, it Wlll' beseen to inserted, the base plates L havingfirst been placed in positionin the shells and held in position by springs 6, 6, which are turned Outas shownin Figs. 1 and 4 so as to remove or replace the shells in thebearingsuE. The

holders with theinserted shells are then swung back against the stops.GQG and red tained bythe -latches H, H and caused 'to V 'slideaxiallyand to approach and press upon the roller M. As before stated,motion is given to the levers K,,K by the levers N, N

and tension rods '0 O, which are actuated by the weight P. Jilqu'alpressure upon the two shells is assured hythefu'lcrum Vof the lever-Qbeing free to slide in the slot W. The roller-M is then .put inaction'by means of; thepulleyv Z and rolls in they base plates-ofthe,shells. y V Having thuszdescribed our invention, what we claim.as new thereimand desire to secure by Letters Patent is v 1; In a machne for rolling 1n base plates I :for explosive shells, a base portion, arolling tool mounted on said'base portion, means to move saidrolllngtool transversely of said base,means .to limit such transversemovement, shell'holders pivotally secured'to said base and adapted tobeswung outward relative to said base, adjustable means forpositlonlngsaid shell holders'on saidbase v -there1n;bear1ngs,aroller'pos1t1onedat one means to retain said shell'holders in posi--tion on said base, means to release said shell holders from operativeposition on said 'baseand automatically operable means for I 5 movingsaid shell holders cooperating posit1on relative'to said rolling tool. j
